Electrical Characteristics 2.17.4 Reception Characteristics (500 kbps) Note: The characteristics are based on pins and functions other than those for the BLE interface not being in use. Note 1. PER ≤ 30.8%, and a 37-byte payload Note 2. Allowable range of difference between the center frequency for the RF input signals and the carrier frequency generated within the chip 2.17.5 Reception Characteristics (125 kbps) Note: The characteristics are based on pins and functions other than those for the BLE interface not being in use. Note 1. PER ≤ 30.8%, and a 37-byte payload Note 2. Allowable range of difference between the center frequency for the RF input signals and the carrier frequency generated within the chip Table 2.75 Reception Characteristics Conditions:VCC = VCC_RF = AVCC_RF = 3.3 V, VSS = VSS_RF = 0 V, Ta = +25°C Item Symbol Min.
